Next generation materials for additive manufacturing
Since the introduction of the SLM process, either existing materials are fabricated or their compositions are altered. As the next step, the aim of this project is to design and develop SLM-specific materials with remarkable properties for various applications. Supervisor: professor Prashanth Konda Gokuldoss.

The aim of this research is to develop next-generation materials for additive manufacturing (AM), especially selective laser melting (SLM). Immiscible alloys (are characterized by the presence of a miscibility gap in their phase diagrams) have gained considerable attention in the last decade due to their valuable properties and potential applications. Non-equilibrium processes like mechanical milling / alloying (MM/MA) were used to process immiscible alloys and to impact a kind of solubility in these alloys. Since SLM is also a non-equilibrium process that can process metallic materials, the focus is to develop next-generation immiscible alloys by SLM.
- Selection of suitable immiscible systems for the SLM process
- Parameter optimization, microstructure, and property correlation in the solidified immiscible systems
- Careful tuning of local microstructures during the SLM processing to attain the defined combination of strength-toughness-ductility
A deeper understanding of the processing of the immiscible systems and their family using SLM will be realized.
